CAR-H EATER.

SPECIFICATION forming part of Letters Patent NO, 380,066, dated March27, 1888.

' Application filed June 13, mm. Serial N6. 241,210. (No model.)

To all whom it may concern:

Be it known that I, J AMEs WARDLE, of Hope, in the Province of BritishColumbia and Dominion of i Canada, have invented a new and usefulImprovement in Car-Heaters, of which the following is a full, clear, andexact description.

. My invention relates to an improvement in car-heaters, and has for itsobject to provide a IO heater which, should the car meet with anaccident and the heater be overturned, will not allow the escape offuel, and wherein the said heater willbe capable of sustaining greatweight and abuse without injury thereto.

1 The invention consists in the construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claim.

Reference is to be had to the accompanying in which similar letters ofreference indicate corresponding parts in both the figures. v

Figure lis a central vertical section through the heater, and Fig. 2 isa front elevation 2 thereof.

In carrying out the invention the stove is constructed of two concentriccylindrical casings of malleable steel or iron, an inner cylinder, A,and an outer cylinder, A, both cylinders being strengthened by outerattached metal hoops or hands, a. Between the said outer and innercylinder a space, B, is made to intervene for the circulation of air, asshown in Fig. 1.

5 Both cylinders are mounted upon and attached to a centrally-aperturedbase, B, secured to the car-floor, and the inner cylinder, A, isprovided with a conical bottom, 0, adapted to project downward throughthe floor flush, or nearly so, with the under side,

above which conical bottom a grate, C, is secured, through which smallcoal and 'cinders may only pass. The outer cylinder, A, is provided witha series of apertures, d, between 5 the encircling hands a, and theinner cylinder, A, is capped by an apertured plate, d, whereby drawings,forming a part of this specification,.

the fuel is not permitted to enter the smokepipe in the event the stoveshould overturn. The top D of the stove is dome-shaped, theflanged'portion thereof being adapted to cover the air-space B.Centrally the dome an aperture is made for the smoke-pipe d A latchedfuel-door, E, is provided in the inner cylinder, and a registeringopening is made in the outer casing, covered by an apertured door, E,adapted to slide upward in ways 6 and operated by a screw-rod, e,attached to the top, which rod travels in a threaded aperture in theflange of the top D by a suitable crank, 6

A crank-rod, F, is projected through the base B and also through thefloor of the car,

having attached to the lower end thereof a horizontal plate, F, whichacts as a damper to control the supply of air to the fire, and also as'a means whereby the ashes may be dumped through the conical bottom 0,the lower aperture of which bottom is normally covered or partiallycovered by the said damper.

From the foregoing description, taken in connection with the drawings,the operation will be readily understood.

Having thusdescribed my invention,what I claim as new, and desire tosecure by Letters Patent, is- 1 I An improved stove consisting of theapertured base B, the outer perforated cylinder, A, secured to the base,the inner cylinder, A, provided with a conical bottom projecting throughthe aperture of the base, the valve F for closing the conical bottom ofthe inner cylinder, the flanged dome D, covering the up- A per ends ofthe said cylinders, and the apertured cap d over the upper end of theinner cylinderand secured between the flange of the dome and the upperend of the inner cylinder, substantially as herein shown and described.

JAMES WARDLE.
